I have the same problem with many items I want.
One that really frustrates me is anodising supplies from Caswell Plating in the US. They have an Aussie distributor and will not deal direct. The Aussie distributor is double the price, considering the distributor is getting this stuff at wholesale prices with the strong $AUD, it's a no-brainer that I have never purchased from them.
Unfortunately I have found no other supplier, not even on ebay
